[origin: EP1892349A1] Container remediation agent (A) comprises an aqueous dispersion, water glass solution (95-98 wt.%) and fiber powder (2-5 wt.%), where liquid phase of the dispersion is a water glass solution, and solid phase from the water glass solution is an insoluble fiber powder particles at a maximum of 50[deg] C. An independent claim is included for the process for remediation of defective containers filled with solid-free liquid by (A) comprising stirring a container liquid (0.4-4 l/1000 l) at 10-30[deg] C, continuously circulating (A) at a time interval of 1-5 days in the container liquid, testing the liquid loss of the container in a temporal distance within the time interval, stopping the liquid loss of the container, lowering the circulation of the container liquid and filtering the excess fiber powder from the container liquid.
